I'm not all that happy about this new data on effectiveness of the vaccines though
I'm way too sceptical of all of it, it's too timing focussed, those with two doses, got vaccinated longer ago, those with one dose got vaccinated more recently. Those with two doses are much older or less healthy, unlikely to have school age kids, move in different groups. Those with one dose are younger, have school children, work more etc.
The data isn't large enough to actually tease out these differences, there aren't enough cases, so it could be in all different directions, the risk reduction of the doses might be completely different, or as described elsewhere (indeed why longer dose strategy was chosen) is that time from first dose matters loads too.
